Why cripple modern machinery and cutting tools with outdated mounting hardware?
Conventional sleeves & bushings = weak links in I.D. turning operations.
From tool tip to machine bed: every connection matters!
ENA boring bar sleeves for small to medium-size bars present a radical departure from standard decades-old designs. Upgrade now to enjoy:
​
-
Increased Rigidity and Chatter Resistance. Special profiles stabilize:
-
the bar inside the sleeve.
-
the sleeve inside the holder.​
-
​​
-
Better Coolant Delivery. A simple and robust sealing system sends coolant through the hole or around the bar (you choose) rather than spraying in all directions.​
​​
-
Easier Set-Up. A wide and un-interrupted indication band facilitates fast and precise alignment of the bar and spindle centerlines, essential for optimal performance.​
​​
-
Greater Durability. Bearing-grade alloy steel fully case-hardened to 60HRC resists scratches, dings and set-screw gouges much better than typical soft or semi-hard sleeve materials.
​​
These benefits are achieved without resorting to restrictive, sensitive and expensive proprietary bar mounting systems. No special holders, tools or procedures are required.
Same M.O. --> Better Results
Works Better + Lasts Longer = Superior ROI...
...and a smaller carbon footprint.
-
Do you run chatter-prone I.D. turning operations such as:
-
Boring of tough alloys?
-
Hard turning?
-
Threading & grooving?
-
High bar length/diameter ratios?
-
-
Do you constantly micro-adjust stick-outs, gingerly dial down cutting data and spend time testing multiple flavors of the same tool type during initial setups?
-
Do you burn inserts and struggle with chip nests due to poor coolant application and inadequate cutting data?
-
Do you shun jobs with extensive I.D. turning due to persistent chatter and the high scrap rates, long cycle times and short tool life that accompany it?
​
Before dismissing your premium machinery or cutting tools as incapable, or to simply accelerate existing operations, please be sure to consider the connection between bars and turret (or B-axis head).
While no boring system is chatter-proof, better sleeves allow cutting tools and machinery to run closer to their full performance potential. Anti-chatter remedies such as “spindle speed oscillation” are all the more effective when the entire insert-to-bed chain is mechanically stable. Controlled coolant delivery, even for bars with flats, is also a welcome development.​​
Adopt early & gain an advantage:
Use quality holders with next-generation ENA sleeves.
